At recommended operating conditions with L/TV
TX_CLK clock period 10 Mbps
TX_CLK clock period 100 Mbps
TX_CLK duty cycle
TX_CLK to MII data TXD[3:0], TX_ER, TX_EN delay
TX_CLK data clock rise (20%-80%)
TX_CLK data clock fall (80%-20%)
Note:
1. The symbols used for timing specifications herein follow the pattern of t
for inputs and t
transmit timing (MT) for the time t
general, the clock reference symbol representation is based on two to three letters representing the clock of a particular
functional. For example, the subscript of t
convention is used with the appropriate letter: R (rise) or F (fall).
